`L'IIVII-IER. B. WALKER, 0F ORANGEVILLE, NEW YORK.

SMUT-MAGHINE.

Specification of Letters Patent No. 1,375, dated October 18, 1839.

To all whom 'it may concern Be it known that I, LUTHER B. WALKER, ofOrangeville, in the county of Genesee and State of New York, haveinvented two new and useful Improvements in Smut-Machines as Used forthe Purpose of Cleansing Wheat and other `'Grrain from Smut and otherImpurities; and I do hereby declare that the following are full andexact descriptions thereof.

The nature of the rst improvement consists in providing the shaft oraxle passing through the machine with two or more beaters, consisting offour or more plates or wings curved in a direction opposite to that oftheir motion and the curvature gradually increasing toward the closedend of the cylinder and also providing the said shaft or axle at theopen end of the cylinder with a small wheel to which are iixed straightplates or wings placed or inserted diagonally across the wheel in thedirection of the curvature of the beat-ers.

The nature of the second improvement consists in applying to the orificeof the cylinder where the wheat or the grain is discharged a tube orspout consisting of two pieces, the one receiving the grain from thecylinder being stationary and closed at its lower end, ascending at asmall angle from the orifice of the cylinder to the side of the frame ofthe machine, the other open at both ends, having on one of its sides amouth or orifice much larger vertically than that of the first piece,playing vertically over the mouth of the first piece or tube and restingupon the wood work of the machine and fastened by keys or springs sothat this upright piece may be elevated or depressed at pleasure, itsmouth always receiving that of the first piece or tube and elsewhereclosed by the wood work or frame of the machine.

The advantages of the first improvement above described are thefollowing: The machine being put in motion, the outer wheel withstraight plates or wings prevents the wheat from escaping and creates astrong draft through the machine, and the peculiar form of the innerbeaters keeps the wheat or other grain almost constantly in contact withthe side of the external cylinder and passes it gradually and constantlytoward the back part of the machine, where it is discharged.

The advantages of the second improvement as connected with the first arethat as the wheat enters the rst part or piece of the spout the strongdraft created by the first improvement it is propelled into the secondor open tube and drops through that tube into suitable repositoriesclean from any smut that may have accompanied it, which is expelledthrough the upper part of the second tube, and the mouth of the secondtube may be elevated or depressed so that the draft will expel upwardonly the smut or smut and chess or smut and chess and oats and shrunkwheat, as may be deemed advisable.

To enable others who understand the art to make and u-se my inventions Iwill proceed to describe their construction and operation.

The drawings accompanying this application, marked A, are merelyintended to present a view of the whole machine.

, A is the external cylinder, through which the axle passes on whichaxle the beaters are fixed. The cylinder consists of the body and theends, one of which is closed and the other open, as represented in thedrawings.

Both ends are of cast iron and are grooved on their circumference so asto receive and lodge the body. The body is of sheet iron and ispenetrated by lines of apertures one inch or two in length running thewhole length. Those apertures are made not by removing any part of theiron but by cut-- ting through and depressing' it, so as to present asharp edge to the wheat when driven against the side of the cylinder bythe beaters. Thro-ugh these apertures which are too small for thepassage of a grain of wheat the smut in part escapes.

B is the open end of the cylinder, C the box or feeder through which thewheat passes into the cylinder, D a part of the first piece of thespout, and E the second or upright piece of the spout.

In the drawings marked B accompanying this application are includeddrawings of the separate parts of the machine including my invent-ions.In those drawings three different views of the cylinder are given allmarked I-I.

The appearance and position of the whirl or wheel which through a strapis connected with the motive power is given in four places and marked F.

No. 4c exhibits the shape and position of the inner and outer beaters.The axle M,

M, runs in a cast iron box at each end and those boxes are fastened tothe wood Work of the machine. The axle at the outer or open part or endof the cylinder is enlarged into a small Wheel, which Wheel, With fourAor more metallic plates or Wings, constitute the outer beaters. Thoseplates or Wings are plane and run diagonally across the Wheel in thedirection of the curvature of the inner beater. The outer beater ismarked L and the inner beater G. The outer beaterhibit different viewsof the upright piece of the discharging spout, and E E E E views of thefirst or receiving part of the spout, which is more particularlydescribed above.

In this drawing there is a plane projecbeaters.

tion of the machine from above or end vievsr and a side vie'w'markedNos. 1,2, 3, respectively. The grain to be cleansed from the smut orchess is fed into the cylinder in the ordinary Way While the axle is inmotion in a direction opposite to the curvature of the The grain afterpassing through the cylinder is discharged below into the spout ordischarging tube as before mentioned.

Vhat I claim as my invention and desire to secure by Letters Patent isf 1. The constructing of smut machines With internal beaters havingcurved plates or Wings as described.

2. And I further claimv in combination With the above the dischargingtubes or spouts as also described. f
